Description:
This gasket set-valve is supplied by the original equipment manufacturer for use with Briggs and Stratton engines commonly installed on lawn and garden equipment. It helps to distribute the pressure evenly and provide an air-tight seal for the cylinder head. Over time components may wear out and begin to crack eventually requiring replacements. For the exact locations and the correct applications, please refer to the appropriate diagrams of your model. This high-quality set includes five composite material gaskets and one valve seal. You will need a wrench set to remove and reattach the cylinder head to perform this repair.

Blown head gasket
I carefully tore down the engine, removing the housing, cover, and then the head. The 8 head bolts must be removed in a pattern gradually to prevent warping or damage. I then used a wire cup brush on my drill and cleaned the piston head and valves and head assembly to remove carbon and buildup, and any remaining grime to assure a good seal with new head gasket. Reassemble, tightening the 8 head bolts in the same gradual pattern, torque to specs. Reassemble top of head, making sure push rods were in correct ports. (one is steel, one is aluminum). Reset valve clearances., new valve cover gasket, with sealant, replaced intake and exhaust gaskets. Engine started righted up, runs like a champ! No smoking, no leaks!

The gasket set comes with two head gaskets and the instructions say to use a single gasket. With one head gasket the engine will not turn over. With two head gaskets the engine started. I did not know
I used the instructions on line for all except the number of head gaskets required.

Intake push rod bent
I jumped the gun initially and pulled the engine from the tractor, thinking the connecting rod had broken. I should have checked the valve push rods first. That would have saved me the time of removing the engine from the tractor and replacing the pan gasket and crankshaft oil seal.
It was pretty simple after I determined that my problem was the push rods. I removed the bent rod installed the new one I purchased from eReplacementParts.com. Adjusted the valves(You can find several youtube videos to guide you through this procedure). The engine started right up and I mowed about two hours with it this weekend.
I wish I could tell you why the push rod bent, but I can't. If anyone has an explnation I would love to here it.

    Good part, bad packaging
    The gasket was folded in half when recieved but i had to use it to get the mower repaired. No reason the gasket needed to be folded in half!

    Good product, aweful packing.
    The gaskets were quality gaskets. However they folded the packaging to fit in a small mailing envelope. While doing it the folded the head gasket in half putting a large crease all the way across it rendering it useless. I had also paid for expedited shipping. I contacted Ereplacmentparts. They took the return but would not send another right away unless I paid for another part and shipping. They wanted me to fund their mistake until they got their useless head gasket back. Good parts, aweful service
